Getting the current Fragment instance in the viewpager

Question

Below is my code which has 3 Fragment classes each embedded with each of the 3 tabs on ViewPager. I have a menu option. As shown in the onOpt

Answer 1

In my Activity I have:

int currentPage = 0;//start at the first tab
private SparseArray fragments;//list off fragments
viewPager.setOnPageChangeListener(new OnPageChangeListener() {

@Override
public void onPageSelected(int pos) {
        currentPage = pos;//update current page
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {}
@Override
public void onPageScrollStateChanged(int arg0) {}
});



@Override
public void onAttachFragment(Fragment fragment) {
    super.onAttachFragment(fragment);
    if(fragment instanceof Fragment1)
        fragments.put(0, fragment);
    if(fragment instanceof Fragment2)
        fragments.put(2, fragment);
    if(fragment instanceof Fragment3)
        fragments.put(3, fragment);
    if(fragment instanceof Fragment4)
        fragments.put(4, fragment);
}

Then I have the following method for getting the current fragment

public Fragment getCurrentFragment() {
    return fragments.get(currentPage);
}
